Dear all, It seems to be a recurrent problem to me and I am asking your help to get over it once for all ... My idea is : I have variables C_1, C_2, C_3 ... that corresponds to vectors of size n, and I would like to cbind them. I get a vector of their names using : temp<- ls(pat="C") And I like to find a way to use this vector temp as an argument to cbind.

Hi R-helpers I would like to plot some planes which are perpendicular to the x-y plane, such as x=y. Is there a way to do this in wireframe? I realize that I am not plotting a function of x, y since there are infinite number of z's that satisfy the above relation.... Hmm... Somewhat related, I would also like to plot a line in 3 d space... Finally, if you are feeling really brave, I

Dear All, I would like to generate m positive real numbers c_i, I=1,...,m, such that (1) c_1 + c_2 + ... + c_m=m, (1) after being ordered into c_1 >= c_2 >= .... >=c_m>0, we have that c_m is of the same order of m^(-1/8), when m is sufficiently large.

Hi, > Both A and B are undef: > LHS = (undef & undef) | (undef & undef) = undef // Since ~undef = undef > RHS = undef > Thus transform is correct. LLVM documentation (http://llvm.org/docs/LangRef.html#undefined-values) suggests that it is unsafe to consider (a & undef = undef) and (a | undef = undef). "As such, it is unsafe to optimize or assume

Thanks for your answers. Another example of unsound transformation on Boolean algebra. According to the LLVM documentation (http://llvm.org/docs/LangRef.html#undefined-values) it is unsafe to consider ' a & undef = undef ' and ' a | undef = undef ' but 'undef xor undef = undef' is safe. Now, given an expression ((a & (~b)) | ((~a) & b)) where a and b are

I'm was wondering if this has been asked about/for multiple exclude-from files ? Where I could find this useful is say I had a common or base exclusion list for all my AIX boxes --exclude-from=/foo/aix_base Then be able to add for say all my AIX boxes that are running SAP --exclude-from=/foo/aix_base --exclude-from=/foo/sap or --exclude-from=/foo/aix-base,/foo/sap and so on ...

*Dear R-help: My name is Rodrigo and I have a question with nlme package in R to fit a mixed beta regression model. I'm so sorry. In the last email, I forgot to say that W is also a unknown parameter in the mixed beta regression model. In any case, here I send you the correct formulation. ** Suppose that:* *j in {1, ..., J}* *(level 1)* *i in {1, ..., n_j}* *(level 2)* *y_{ij} ~

I have the adjacency matrix of a graph. I'm trying to find all triangles (embeddings of C_3). This doesn't work: index = function(l) seq(l)[l] pairs = do.call(rbind, lapply(seq(nrow(adj)), function(x) cbind(x, index(adj[x,])))) triangles = do.call(rbind, apply(pairs, 1, function(x) cbind(x, index(adj[x[1],] & adj[x[2],])))) I'm absolutely certain I've gone down the wrong path

*Dear R-help: My name is Rodrigo and I have a question with nlme package in R to fit a mixed beta regression model. The details of the model are: Suppose that:* *j in {1, ..., J}* *(level 1)* *i in {1, ..., n_j}* *(level 2)* *y_{ij} ~ Beta(mu_{ij} * phi_{ij}; (1 - mu_{ij}) * phi_{ij}) y_{ij} = mu_{ij} + w_{ij} * *with* *logit(mu_{ij}) = Beta_{0i} + Beta_{1i} * x1_{ij} + b2 * x2_{ij}

Hi, Anybody can give me some hints on the following problem? s<-c(1101111,112321) I want to insert a dot "." after the third number and get the following results. 110.1111 112.321 Thanks a lot. -- ----------------- Jane Chang Queen's [[alternative HTML version deleted]]

Hi all, rmvnorm()can be used to generate the random numbers from a multivariate normal distribution with specified means and covariance matrix, but i want to specify the correlation matrix instead of covariance matrix for the multivariate normal distribution. Does anybody know how to generate the random numbers from a multivariate normal distribution with specified correlation matrix? What about

Hi all, Today, i just installed the newest R version 2.10.1 and other necessary tools for building R package under windows,e.g. Rtools, perl. All are the newest version. After the correct configuration under windows, i use it to re-check my old package. I found the following prolem when checking EXAMPLE, which did not exist before this re-installation. ######## * checking examples ... ERROR

Hi Rusers, I found sometimes that the same values cannot be judged to be the same in R. Anybody knows the probelm? I think i ignored some minor detail. Thanks.

Hi: I've been reading "Computational Methods for Multilevel Modeling" by Pinheiro and Bates, the idea of embedding the technique in my own c-level code. The basic idea is to rewrite the joint density in a form to mimic a single least squares problem conditional upon the variance parameters. The paper is fairly clear except that some important level of detail is missing. For

Hi all, I want to put several figures in a one figure for easy comparison, so i need to use the same methods to plot these figures. The following is an example. I also list my method, but it does not work. #Example data x<- 1:10; y<- 1:10; z<- outer( x,y,"+");z2<- outer( x,y,"-") #Quick view them image.plot(x,y,z) #relatively larger value image.plot(x,y,z2)

Hi, I know we can use 1:10 to represent the 1,2,3,...,10 numbers, but the following conditions are except. Anybody knows how to represent the following two cases with similar usage of ":" or others? Usually, i will get several hundred names for them, such as a1,a2,... or f[[1]],f[[2]],... #Example data a1<-array(1:12,c(2,3,2)); a2<-array(2,c(2,3,2)); a3<-array(0,c(2,3,2))
